We may have our first hint at where Valve is going with the first slate of downloadable content for Left 4 Dead 2. Fans have discovered a website for the motorcycle-riding metal band Midnight Riders, which, according to official records, was registered by Valve on September 10 and teases "coming soon."

Left 4 Dead 2 players might remember the Midnight Riders from the end of the creepy Dark Carnival campaign. Survivors are tasked with turning on the Midnight Riders' stage as they try to escape.
